Budget Development Process
Phase 1: Preliminary Estimate
Early planning requires rough order of magnitude estimate:
- Based on similar projects
- Per-square-foot comparisons
- Feasibility analysis
Purpose: Determine if project is financially viable.
Phase 2: Schematic Design Budget
Once design direction set:
- Detailed cost estimate for preliminary design
- Breakdown by system and component
- Identification of major cost drivers
Purpose: Validate design approach; adjust if needed.
Phase 3: Design Development Budget
As design becomes more specific:
- Detailed quantity takeoffs
- Specific material and equipment pricing
- Labor rate estimates
- More accurate contingency
Purpose: Refine estimate for budget lock.
Phase 4: Construction Document Budget
Final estimate before construction:
- Complete specifications and materials
- Quantity and specification-based pricing
- Detailed labor estimates
- Bid solicitation from contractors
Purpose: Establish construction budget.
Phase 5: Cost Control During Construction
Ongoing cost management:
- Change order tracking
- Value engineering for cost savings
- Procurement optimization
- Schedule efficiency monitoring
Purpose: Keep project on budget.

Contingency Planning
Why Contingency is Necessary
Construction always involves unknowns:
- Hidden conditions discovered during excavation
- Design changes requested during construction
- Weather delays
- Material availability issues
- Labor challenges
- Code interpretation questions
Appropriate Contingency
Early Project (Feasibility): 20-30% contingency
- Significant unknowns
- Rough estimates
- High uncertainty
Design Phase: 10-15% contingency
- Design becoming more detailed
- Estimates more accurate
- Some unknowns remain
Bid Phase: 5-10% contingency
- Design complete
- Contractor pricing basis
- Risk lower but not eliminated
Construction: 3-5% contingency
- Limited unknowns remaining
- Use for genuine surprises
- Careful contingency management
Contingency Management
Protect contingency:
- Use for genuine unknowns only
- Don’t use for design changes
- Don’t use for poor planning
- Keep contingency reserve separate
Value Engineering
Reducing cost without compromising quality:
Material Substitution
- Choose materials meeting codes at lower cost
- Local materials instead of imported
- Durable basic materials instead of premium finishes
Simplification
- Simplify designs reducing complexity
- Standard components instead of custom
- Reduced site complexity
Sequence Optimization
- Efficient construction scheduling
- Reduced inefficiencies
- Minimized weather exposure
Scope Modification
- Reduce scope to essentials
- Phase project over time
- Defer non-essential features
Value engineering should enhance value, not reduce quality.
